Load Balance 2 Wireless Controllers?

drewgon2010 — Sun, 04 Jul 2021 02:28:12 GMT

Hi Guys,

We are running 2 Cisco wireless controllers here..I believe a 4400 and a 5500..

All our WAPS and Clients are going to the one Individual Controller..Is it possible to load balance all waps/clients between these?

Thanks

James

I wouldn't go for that. Inter-controller roaming can sometimes cause issues with the back-end.

I support this answer. If you plugged your WLC with all ports on LAG, what are you exactly load balancing ? Nothing will be faster by splitting APs between the 2 WLCs.

In case you anyway split the APs between the 2 WLCs, don't go salt 'n pepper (i.e. if you have 2 APs in a corridor, having them on a different wlc) because that means that every roaming between APs will be inter-WLC roaming. Overhead for nothing. It's best to cut your building in 2 and one are is on wlc1 and the other on wlc2.

While inter-WLC roaming usually works fine and should not cause trouble, it's overhead to go for that while you can have all APs on 1 WLC.
